Specification of'Letters Patent. Patgnfigd i 1L 1912iApplication.filedSeptember 20, 1912. Serial No. 721,506.

To all whom it may cdncern Be it known that 1, GEORGE W. Heine/inns, acitizen of the United States, residing at 'Billings, in the county ofYellowstone and State of Montana, have invented a new and usefulPlowshare, of which the follow ,ing is a specification.

The present invention aims to prgvide novel means whereby the share of aplowmav be assembled readily with the land side and with the 'moldboardof the plow,

and with equal facility, be removedtherefrom.

The invention aims, further, to provide a structure of this type whichwill render the connection between the share and the body portion of theplow secure, the several parts of the plow being braced and sustainedwith respect to each other.

It is within the scope of the invention to improve generally and toincrease the utility of, devices of that type to which the resentinvention appertains.

"With the foregoing and other objects in view which will appear as thedescription proceeds, the invention bination and arrangement of partsand in the details of construction herein after described and cla-imeditbeing understood that changes in the precise embodiment of invent-ion.herein disclosed can be made within the scope of what is claimed.without departing from the spirit of the inventi'on. I

1n the accompanying drawings :--F igure 1 shows the invention' in sideelevation; Fig. 2 is a bottom plan; Fig. 3 is a perspective of the plowshare; Fig. 4L. is a perspective of the tie and parts carried thereby;Fig. 5 is a perspective of one of the braces; and Fig. 6 is a sectionalelevation show ng a portion of the frog.

In the accompanying drawing, theaumeral 1 indicates the mold board andthe resides in the comheaded stud 9,- rec'eived within a. rearwardlyinclined, open ended slot 10 formed in line edge of the crown piece 3.Projecting from the'mold board section 5015 thegshare 4: is a headedstud 11 received within a rear- ,wardly inclined, openended slot 12;formed in one wing of the frog 3, as shown most clearly 1n Fig. 2. Tothe rear ofthestud '11, the mold board section 50f the share 1isprovided with another-headed stud 14.

The invention further includes abrace, denoted by the numeral 15, thebrace 15 being provided at its ends with feet 16 and 17, the foot 16being secured to the land side 2, and the foot 17 being secured to themold board 1. The foot 17 is provided with an extension 18 whichoverlies the inner face of the moldboard section 5 of the share therebeing a notch 19' in the outer end of the extension 18, receiving thestud 14 and fitting beneath the head-of the stud. The extension 18 istapered or wedge-shaped toward its free end, so that when the stud 14 isreceived within the notch 19, the extension 18 will be held between thehead of the stud 14 and the mold board section 5. Intermediate its ends,the

brace 15 is equipped with thedepending lug 21 in which is-mounted toslide, transversely of the brace 15, a tie which is denoted bythe'numeral 23. At the forward end, the tie 23 is equipped with a head24:

having a key-hole slot25 in which the stud 11 is received. The head 24:is thickened or rendered wedge-shaped, toward its free end, so that whentension is exerted upon the tie 2s, tween the head of the stud 11 andone wing of the frog 3. Projecting from one end of the tie 23 is'a pin27'supporting for rotation a cam 28 provided with a handle 29. The cam28 is adapted to bear against the the head 24 may be wedged tightly ,7

rear face of the lug 21 and against the rear face of the brace 15.Another brace 22 extends from the brace 15, adjacent the land side 2,into engagement with the mold board 1.

Y The operation of the device herein disclosed is as follows :The share4 is engaged with the mold board 1, with the land side 2, and with thefregf3, as is common, the stud 11 entering the slot 12. The key-holeslot 25 of the tie 23 is engaged with the stud 11 which projects fromthe mold board section 5 of the share, the stud 14 upon the mold section5 entering the slot 19' in the section 18 of the brace 15. The handle 24of the cam 28 is then swung, causing the Calif 28 to bear against thelug 21 and against the rear edge of the brace 15, whereupon the tie 23will he slid longitudinally, and transversely jotthe brace 15, the share4 beingdrawn reamvardly. During this operation, the wedge-shaped end 26of the tie 23 will bear against the head of the stud 11, the stud 11being retracted into the slot 12 formed in one wing of the frog'3. Atthe same time,

the stud 14 will be drawn rearwardly into the notch 19- and the taperedwedge-shaped end-18 will be bound between the head of the stud l4 andthe mold board section 5.

Having thus described the invention what is claimed is1 1. In a plow, aland side; a mold board; a share comprisinga land side section and amold board section; a brace connected with the land side and with themold board, the

brace having a slotted "extension overlying the mold boardsection of theshare, said section having a stud registering in the slot of theextension; a tie slidable transversely of the brace, the tie and themold board section of the share having interengaging elements; and meansupon. the tie for engaging the brace to slide the tie.

2. In a plow, a fro having a slot; a land side and a mold boar carriedby the frog, a] share comprising a land side section and a mold boardsection, the land side section having a. stud received in the slot; abrace connected with the land side and with-the mold board, the bracehaving a slotted extension overlying the mold board section of theshare, said section having a stud registerin g in the slot of theextension; a tie slidable transversely of the brace, the tie and themold board section of the share having intereng'aging elements; movablemeans cooperating with the tie and with the brace for sliding the tie;and another brace connecting the first specified brace with the moldboard. l
